Struct OrderedSet 

pub struct OrderedSet { /* private fields */ }

A type wrapping indexmap::IndexSet

Implementations

impl OrderedSet

pub fn new() -> OrderedSet

Creates a new empty OrderedSet.

pub fn with_capacity(capacity: usize) -> OrderedSet

Creates a new empty OrderedSet with the specified capacity.

pub fn full_len(&self) -> usize

Return the number of elements in the set, including empty elements.

Computes in O(1) time.

pub fn len(&self) -> usize

Return the number of elements in the set.

Computes in O(1) time.

pub fn is_empty(&self) -> bool

Returns true if the set contains no elements.

Computes in O(1) time.

pub fn add(&mut self, value: JsValue) -> bool

Insert a value pair in the set.

If an equivalent value already exists in the set: ???

If no equivalent value existed in the set: the new value is inserted, last in order, and false

Computes in O(1) time (amortized average).

pub fn delete(&mut self, value: &JsValue) -> bool

Delete the value from the set and return true if successful

Return false if value is not in set.

Computes in O(n) time (average).

pub fn clear(&mut self)

Removes all elements in the set, while preserving its capacity.

pub fn contains(&self, value: &JsValue) -> bool

Checks if a given value is present in the set

Return true if value is present in set, false otherwise.

Computes in O(n) time (average).

pub fn get_index(&self, index: usize) -> Option<&JsValue>

Get a key-value pair by index Valid indices are 0 <= index < self.len() Computes in O(1) time.

pub fn iter(&self) -> impl Iterator<Item = &JsValue>

Return an iterator over the values of the set, in their order

Trait Implementations

impl Clone for OrderedSet

fn clone(&self) -> OrderedSet

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OrderedSet

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for OrderedSet

fn default() -> OrderedSet

Returns the “default value” for a type.

impl Finalize for OrderedSet

fn finalize(&self)

Cleanup logic for a type.

impl Trace for OrderedSet

unsafe fn trace(&self, tracer: &mut Tracer)

Marks all contained Gcs.

unsafe fn trace_non_roots(&self)

Trace handles located in GC heap, and mark them as non root.

fn run_finalizer(&self)

Runs Finalize::finalize on this object and all contained subobjects.
